Plumbing Installation Instructions
Steambath Generator Model: SM-11
The Steamist “SM” Generator comes factory assembled,
carefully wired and tested.
WARNING: All electrical power should be turned OFF when
working with Steam Generator.
IMPORTANT: The Plumbing Installation must conform to local
and national codes.
1. Pre-Installation
a) Be sure that the proper size Steam Generator has been
selected by using the sizing page in the “Full Line
Brochure,” “Pricing Guide,” “The Generator Sizing
Guide,” “Architectural Guidelines,” or in the Residential
Systems/Steambath Product Information section of the
Steamist website - www.steamist.com.
CAUTION: An improperly sized Steam Generator may NOT
produce the amount of steam necessary to reach selected
temperature.
b) For optimum performance, the Steam Generator should
be located as close as possible to the Steamroom,
Shower or tub enclosure using a ¾” copper pipe (1/2”
copper pipe is also acceptable, but not preferred). If the
steam pipe exceeds ten feet, it should be insulated using
appropriate pipe insulation rated for a minimum of 212º F.
Maximum steam pipe distance should not exceed a total
of fifty linear feet. Refer to Installation Suggestions on
page 4.
CAUTION: Do NOT install near flammable material such as
paints, thinners, gasoline, etc.
CAUTION: Steam generators must NOT be installed outdoors, in
moist, humid areas, in areas prone to freezing, or extreme heat
such as an unventilated attic. To do so will void the warranty.
c) The steam line and safety valve reach a temperature of
212°F during operation and should be appropriately
protected to prevent personal injury by accidental
contact.
2. Plumbing Rough-in
Plumbing rough-in is required for the water supply and
steam line; this should be completed before the walls
are closed. For operation, the “SM” Steam Generator
requires a ⅜" O.D. copper tubing to the fitting on the
generator for water inlet and a ¾" copper or brass pipe
for steam outlet.
NOTE: Safety Valve should be connected using a union to a
minimum ¾" indirect waste or as required by local plumbing
codes. In the unlikely event this valve should open, the
discharge must be directed to prevent damage to the home.
Do NOT connect the Safety Valve output to the steam line.
a) Water Inlet - Rough in a water line, 120 PSI max,
to the hot or cold supply. A shut off valve with a
3/8” connection to the steam generator is to be
provided at the generator location (see Figure 4 on
page 3).
b) Steam Outlet - Rough in the steam line using a ¾”
Brass pipe or Copper tube with sweated fittings
only. Do NOT use plastic pipe or fittings. Do not
use any push-fit, snap-fit or anything else that is
not specifically rated for 212ºF steam. Do NOT use
Black Iron or Galvanized pipe to avoid rust and
discoloration to steam room. The steam head
location should be 12” to 18” above the steam
room floor or 6” above a rim of a bathtub and as far
from the seating area as possible.
CAUTION: No shutoff valve can be installed in the steam
line. Do NOT create traps or valleys in this line which would
trap condensation and block the flow of steam. The steam
pipe should be pitched toward the Steam Generator
allowing condensation to run back toward the Steam
Generator (preferred), or toward the steamhead. If the
steam generator is equipped with a drain valve, do NOT
connect the drain pipe to the steam line.

IMPORTANT: The warranty of this product is voided if it is used in a commercial application or for anything other than a residential
steambath installation. This product is not intended for use with Home Automation systems.
Important: Locate Publication No. 199 “Steam Bath Important Safety Instructions”. This publication includes a Warning
label that the contractor must install on the wall near the entrance to the steam room in a highly visible location. This
label and its additional safety information are packaged with the generator in the envelope containing the installation
instructions. If it is lost or missing contact Steamist (201-933-0700) for a replacement Publication No. 199. This publica-
tion along with all documents must be left with the owner.

3. Steam Generator Installation
The Steam Generator should be mounted in a location
convenient for hook-up and service by the plumber and
electrician.
CAUTION: The Steam Generator is designed to be used
ONLY in an upright and level position; to do otherwise would
damage the unit and void the warranty.
a) The Steam Generator can be mounted to a wall or
set on the floor. However, the unit must be secured.
To secure the unit to a vertical wall, loosen the two
screws holding the electrical access cover, remove
cover (see Figure 1). Located inside the cabinet
near the top left and right corners are mounting
holes. Place top cover back and secure.

b) Connect the ⅜" water inlet to a shut off valve as
described in Section 2.a. The valve must be kept in
an open position during normal operation. In an
area where water hammer is a problem install a
water hammer arrestor in the line. Refer to Figure
2.
IMPORTANT: Do NOT use a “saddle valve” or
piercing type valve for water connection.
c) Connect the steam line from rough-in location
described in Section 2 to the ¾" nipple on the
Steam Generator using a union.

The Plumbing Instructions must be given to the homeowner for future use.
